2020-11-20 Hematite positive-reverse flotation separation means that the slurry finishes positive flotation first to scrape out the hematite concentrate foam, then get sent to another flotation machine for reverse flotation, and the hematite concentrate is enriched in the flotation cell finally. Commonly used collector is dodecylamine.
2015-12-9 The application of vacuum hematite flotation machine in the production practice is less.Xinhai Mining company is an international well-known hematite flotation machinery manufacturers, it produces specifications of the various types of magnetic separation equipment and flotation equipment such as hematite wet hematite process equipment, the
2015-12-24 The technology of hematite flotation is very important to the hematite beneficiation process. 5% stearic acid, 80% oleic acid, 10% linoleic acid and 1% linolenic acid. But soon the problem of piecewise pumping foam is increasingly evident. Xinhai produces all kinds of hematite separation and flotation equipment and produces all kind of
2003-4-2 flotation (hematite flotation) or indirect flotation (quartz flotation) tech-niques depending upon the nature of the available ore bodies. In direct flota-tion, iron bearing mineral, mostly hematite, is floated using oleate as collec-tor leaving siliceous gangue, usually quartz, in the tailings. Kick et al. [1]
2021-1-1 The results of a number of comparative flotation characteristics of hematite flotation using the 18-carbon fatty acids are summarised in Table 2.The general trend was that the unsaturated fatty acids were stronger collectors for hematite compared with stearic acid, with an increased amount of double bonds/molecule often giving higher flotation recoveries.

2016-3-8 Xinhai majors in manufacturing hematite iron ore processing equipment, such as crusher, grinding mill, flotation cell, magnetic equipment, gravity separating and so on. Follows are a brief introduction of flotation cell of Xinhai and the brief introduction of extraction of iron from hematite.
2018-10-2 Given the gradual increase in the chlorite content of hematite ores, pulp properties seriously deteriorate during flotation. The traditional anion reverse flotation of hematite cannot effectively eliminate the effects of chlorite, leading to a significant decrease in the total Fe (TFe) grade of the concentrate. In this work, the effect of sodium alginate on the reverse flotation of hematite
2017-11-1 Natarajan (1978) also reported a minimum in hematite flotation from a low grade iron ore at pH 5 using sodium oleate and pine oil, and a maximum in hematite recovery at pH 9. Peck et al. (1966) reported a flotation maximum at pH 7, and a flotation minimum at pH 8 for the flotation of a synthetic hematite with a high surface area (76 m 2 /g
2007-8-1 The flotation experiments with mixtures containing 75% of hematite and 25% of quartz, the recovery of hematite was around 90.7% with a concentrate grade of 86.0% Fe 2 O 3. The relationship between depressant and collector concentration was shown to be a particularly critical parameter.
Another important use of flotation is to reduce ash in fine coal and to remove fine pyrite from coal. There are billions of tons of ore and materials that are processed by flotation every year in the world. The large ore processing plant processes 100,000 tons of ore per day. The production index and equipment efficiency of flotation are high.

Hematite is easier to floated than magnetic, which could be separated by positive flotation. As the density of iron ore is much higher than that of gangue mineral, gangue mineral is more likely to attach to the foam than iron ore. Therefore, for iron ore, reverse flotation is more advantageous than positive flotation.
